Retrieval of fractured root

A) When a larger portion of the tooth root is left behind after extraction of the tooth, the small straight elevator can sometimes be used as a wedge to displace the tooth in the occlusal direction. It must be remembered that the pressure applied in such a fashion should be in gentle to-and-fro motions; excessive pressure should not be applied. (B) Excessive pressure in the apical direction results in displacement of the tooth root into undesirable places such as the maxillary sinus.
